Diamix L - Compamix L MIXING/THERMOREGULATING MOTORISED VALVES FOR DOMESTIC HOT WATER WITH ANTI-LEGIONELLA FUNCTION DISINFECTION CYCLE ALARMS If the hot water temperature is not high enough (temperature below 55°C for 60 minutes) the alarm “ALbt” is activated, the cycle fails and the regulator automatically resumes the mixing function. If there is no power supply, the “ALd” alarm is activated, the cycle fails and the regulator automatically resumes the mixing function. The disinfection cycle can not last more than 300 minutes: if the cycle does not finish in time, the “ALot” alarm is activated,...

Diamix L - Compamix L MIXING/THERMOREGULATING MOTORISED VALVES FOR DOMESTIC HOT WATER WITH ANTI-LEGIONELLA FUNCTION REMOTE MANAGEMENT – RTU MODBUS and Compamix L are equipped with RTU MODBUS interface and it is possible to modify all the operating parameters, send commands to the valve, receive information on the operating status and download the data of the stored thermal disinfection cycles using the RS485 serial connection. Diamix L and Compamix L mixing valves are suitable for connection with modern Building Management Systems (BMS). The Modbus address table can be downloaded from www.comparato.com....

Diamix L - Compamix L MIXING/THERMOREGULATING MOTORISED VALVES FOR DOMESTIC HOT WATER WITH ANTI-LEGIONELLA FUNCTION ASSEMBLY NOTES: The pipe section where the temperature probe will be placed must be made of metal. The following part of the pipe can be of any type, provided it is suitable to the use. Once the ball valve has been installed, the actuator can be rotated 180°. Mounting the actuator facing downwards is not allowed. Position the check valve on the recirculation pump outlet. INSTALLATION The valve should be installed in such a way that the actuator connection is not facing downwards....
